IQ Signal Master™ MX280005A Vector Signal Analysis Software : View Mode : Audio Demodulation : Points of Interest
 
Points of Interest
Refer to Figure: Points of Interest Window. The Points of Interest window is populated when the binoculars icon is pressed and searches the modulation data set to find points on the signal that show the most change. The Reason column displays a brief description of the captured point of interest. Right-click a point of interest to show the context menu for further analysis or distribution.
Points of Interest Window
For details of the Points of Interest window, see Table: Points of Interest.
Points of Interest
3-bar Icon
Press to provide the content menu shown in Figure: Points of Interest Window. Right-click the Points of Interest table provides the same context menu.
Remove Selected Points of Interest
Click one or multiple points from the Points of Interest table and click Remove Selected Points of Interest to delete them from the table.
Copy Table to Clipboard
Copies the entire Points of Interest table into the clipboard.
Copy Point of Interest to Clipboard
Copies a selected Point of Interest from the table into the clipboard.
Copy Time Offset to Start
Copy the time offset value of the selected Point of Interest into the Convert menu Start (ms) field.
See Trim Adjust Window.
Copy Time Offset to End
Copy the time offset value of the selected Point of Interest into the Convert menu Stop (ms) field.
See Trim Adjust Window.
Copy Time Offset to Analysis
Copy Time Offset value to the Analysis Menu.
Copy Time Offset to Synchronized Playback
Copy the Time Offset value into the Synchronized Playback Menu Playback Offset field for that file.

Sensitivity Slider
Slide left provides a less sensitivity search where the bandwidth search is large and will result in the most significant signal changes. Slide right provides a more sensitive search where the bandwidth search is smaller and will result in capturing more signal point changes, but some changes may be less detectable when viewed on the graph display.
Find Icon
Press to search for the Points of Interest of the I,Q, and M signal display. As points of interest are located, the signals parameters are logged as shown in Figure: Points of Interest Window. The field updates each time the resolution slider is moved to increase or decrease resolution,
Sample
Location of the POI. The sample number at which the signal change occurs.
Time (µs)
Time of the occurrence. (Sample / sample rate)
Reason
Type of signal change flagged as a POI. (Power shift or Modulation shift)
Depth
A dimensionless measure of how much the modulation or power has shifted. It is useful when comparing between entries in the table. You can sort on each column by clicking the column title. So ‘Depth’ is in the table so you can sort and see the points that had the largest power or modulation shift at the top of the list.
Select Points of Interest
Right-click a data set in the Power vs. Time graph to display the “Add location to Points of Interest” tool tip shown in Figure: Select and Display Points of Interest. Click the dialog to select a point of interest and display it in the Points of Interest table.
